At any suitable point along the arm of thelever A (preferably about onethird of the distance from, the block B tothe other end of the lever A) is provided the plate C, made of metal orany suitable material. Just beyond the plate C is pivoted the eccentricclamp D, provided with a roughened or serrated periphery, and with ahandle, d, for

operating it, in its function of grasping and retaining a wire betweenthe eccentric clamp D and the plate C, as will hereinafter more fullyappear.

In operating our device, place the revolving block B against the fenceor telegraphpost, or to whatever the wire is to be secured. While inthis position the spurs b h will enter the post, and prevent anyslipping or displacement. Now carry the lever A forward, and place thewire to be stretched between the plate C and eccentric D, and clamp itthere by a turn ofthe arm or handle d. It will now obviously appear thatby a return :movement of the lever A the Wire, firmly heid as it isbetween the plate C and eccentric D, Will be stretched to the desiredtension, when it may be secured in any suitable way.
